+
+This script help you migrate from a pre-1.7 database to 1.7 and later\n
+Both the 'calendarobjects' and 'calendars' tables will be upgraded.
+
+If you do not have this table, or don't use the default PDO CalDAV backend
+it's pointless to run this script.
+
+Keep in mind that some processing will be done on every single record of this
+table and in addition, ALTER TABLE commands will be executed.
+If you have a large calendarobjects table, this may mean that this process
+takes a while.
+
+Usage:
+
+php {$argv[0]} [pdo-dsn] [username] [password]
+
+For example:
+
+php {$argv[0]} "mysql:host=localhost;dbname=sabredav" root password
+php {$argv[0]} sqlite:data/sabredav.db
